Abstract

The invention relates to an industrial manufacture method for hydrogenated petroleum resin, which comprises the following steps of: generating hydrogenation reaction on petroleum resin which is obtained by polymerizing cracking C5 and C9 fractions under the proper condition of the existence of hydrogenation catalyst and solvents by adopting the processes of two-section hydrogenation and combination alkaline cleaning neutralization; hydrogenating the unsaturated component in the petroleum resin to reduce double-bond content; hydrogenating a non-ferrous perssad to fade; hydrogenating to remove chlorine retained in the polymerization process; and carrying out alkaline cleaning, water cleaning, stabilizer injection and solvent removal to obtain light or colourless hydrogenated petroleum resin. The method further simplifies the process through the organic combination of unit operation, and the industrial manufacture method for the hydrogenated petroleum resin, which has the advantages of wide adaptability on hydrogenated raw materials, less corrosion on system equipment, high product quality and high production capability is formed.

Description

technical field [0001] The invention belongs to an industrial manufacturing method of petroleum resin, in particular to an industrial manufacturing method of hydrogenated petroleum resin. Background technique [0002] In the process of producing ethylene and propylene by steam cracking of petroleum fractions, a large amount of cracked C5 and C9 fractions will be produced by-products, which are usually used as raw materials for the production of petroleum resins. Thermal polymerization or catalytic polymerization methods are used. After pretreatment, polymerization, desolventization, Sheet forming and other processes (catalytic polymerization also includes catalyst removal, neutralization, water washing and other processes), to produce various specifications of C5, C9 petroleum resin or C5 / C9 copolymerized petroleum resin (molecular weight is generally around 500-2000), called It is unhydrogenated petroleum resin. Due to the different raw materials used and the polymerizatio...
